汇总各个部门当前员工的title类型的分配数目，结果给出部门编号dept_no、dept_name、其当前员工所有的title以及该类型title对应的数目count

CREATE TABLE `departments` (
`dept_no` char(4) NOT NULL,
`dept_name` varchar(40) NOT NULL,
PRIMARY KEY (`dept_no`));
CREATE TABLE `dept_emp` (
`emp_no` int(11) NOT NULL,
`dept_no` char(4) NOT NULL,
`from_date` date NOT NULL,
`to_date` date NOT NULL,
PRIMARY KEY (`emp_no`,`dept_no`));
CREATE TABLE IF NOT EXISTS `titles` (
`emp_no` int(11) NOT NULL,
`title` varchar(50) NOT NULL,
`from_date` date NOT NULL,
`to_date` date DEFAULT NULL);

输入描述:

无

输出描述:

dept_no	dept_name	title	count
d001	Marketing	Senior Engineer	1
d001	Marketing	Staff	1
d002	Finance	Senior Engineer	1
d003	Human Resources	Senior Staff	1
d004	Production	Senior Engineer	2
d005	Development	Senior Staff	1
d006	Quality Management	Engineer	2
d006	Quality Management	Senior Engineer	1

思路：看创建的表以及结果：tiltle是惟一的，需要的是 departments表和title表里面的dept_no，dept_name和title以及title的重复计数，但是departments和title表没有直接关系，

1.连接dept_emp和titles表，判断to_data=‘9999-01-01’ ，d.emp_no=t.emp_no
2.连接department和1操作之后的表，条件dept_no==
3.group by dept_no,title

SELECT de.dept_no, dp.dept_name, t.title, COUNT(t.title) AS count
FROM titles AS t INNER JOIN dept_emp AS de 
ON t.emp_no = de.emp_no AND de.to_date = ''9999-01-01'' AND t.to_date = ''9999-01-01''
INNER JOIN departments AS dp 
ON de.dept_no = dp.dept_no
GROUP BY de.dept_no, t.title

select dp.dept_no, dp.dept_name, t.title, count(t.title) as count 
from titles as t inner join dept_emp as de
on t.emp_no = de.emp_no and t.to_date = ''9999-01-01''and de.to_date = ''9999-01-01''
inner join departments as dp
on de.dept_no = dp.dept_no
group by t.title ，de.dept_no   --group by 后面的顺序修改，输出顺序不同，不是输出描述中所需要的表，导致出错不通过

2022-12-05：部门工资前三高的所有员工。编写一个 SQL 查询找出每个部门中收入前三高的员工。 +------------+----------+--------+ | Department |

2022-12-05：部门工资前三高的所有员工。编写一个 SQL 查询找出每个部门中收入前三高的员工。 +------------+----------+--------+ | Department | Employee | Salary | +------------+----------+--------+ | IT | Max | 90000 | | IT | Joe | 85000 | | IT | Randy | 85000 | | IT | Will | 70000 | | Sales | Henry | 80000 | | Sales | Sam | 60000 | +------------+----------+--------+

DROP TABLE IF EXISTS `department`;
CREATE TABLE `department` (
  `id` int(11) NOT NULL,
  `name` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

INSERT INTO `department` VALUES (''1'', ''IT'');
INSERT INTO `department` VALUES (''2'', ''Sales'');

DROP TABLE IF EXISTS `employee`;
CREATE TABLE `employee` (
  `id` int(11) NOT NULL,
  `name` varchar(255) NOT NULL,
  `salary` int(11) NOT NULL,
  `department_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

INSERT INTO `employee` VALUES (''1'', ''Joe'', ''85000'', ''1'');
INSERT INTO `employee` VALUES (''2'', ''Henry'', ''80000'', ''2'');
INSERT INTO `employee` VALUES (''3'', ''Sam'', ''60000'', ''2'');
INSERT INTO `employee` VALUES (''4'', ''Max'', ''90000'', ''1'');
INSERT INTO `employee` VALUES (''5'', ''Janet'', ''69000'', ''1'');
INSERT INTO `employee` VALUES (''6'', ''Randy'', ''85000'', ''1'');
INSERT INTO `employee` VALUES (''7'', ''Will'', ''70000'', ''1'');

答案 2022-12-05：

sql 语句如下：

SELECT
    d.Name AS ''department'', e1.Name AS ''employee'', e1.salary
FROM
    employee e1
        JOIN
    department d ON e1.department_id = d.id
WHERE
    3 > (SELECT
            COUNT(DISTINCT e2.salary)
        FROM
            employee e2
        WHERE
            e2.salary > e1.salary
                AND e1.department_id = e2.department_id
        )
;

执行结果如下：

在这里插入图片描述

add the push notifications entitlement to your entitlements file

我点击 Fix Issue,这个问题就会消失，然后去其他界面再回来，还是这个问题。

也能正常运行，就是收不到推送

.entitlements 文件双击打开提示：The data couldn’t be read because it isn’t in the correct format.

用记事本打开这个 .entitlements 文件

发现格式不正确

添加一句

android-table game没有名为title：的列,而在编译时：INSERT INTO game(title,rating,info)VALUES(？,？,？);

尝试将项目插入数据库时出现错误.

这是Logcat读取的内容：

android.database.sqlite.sqliteException table game has no column named title: , while compiling: INSERT INTO game(title, rating, info)  VALUES (?, ?, ?);

这是我的数据库管理器：

package com.herring.android.finalproject;

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlException;
import android.database.sqlite.sqliteDatabase;
import android.database.sqlite.sqliteOpenHelper;
import android.util.Log;

public class GameDataBaseManager {

    private DatabaseHelper mDbHelper;
    private sqliteDatabase mDb;
    private static final String DATABASE_NAME = "data";
    private static final int DATABASE_VERSION = 1;  
    private final Context mCtx;
    private static final String GAME_TABLE_NAME = "game";
    public static final String KEY_ROWID = "_id";
    public static final String KEY_TITLE = "title";
    public static final String KEY_BODY = "info";
    public static final String KEY_rating = "rating";
    private static final String GAME_TABLE_CREATE = "create table " + GAME_TABLE_NAME + " ( " + 
            KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
            KEY_TITLE + " TEXT NOT NULL, " +
            KEY_BODY + " TEXT NOT NULL, " + 
            KEY_rating + " NUM NOT NULL );";


    public GameDataBaseManager(Context ctx)
    {
        this.mCtx = ctx;
    }


    public long addRow(String rowStringOne, String rowStringTwo, float rating)
    {
        ContentValues values = new ContentValues();
        values.put(KEY_TITLE, rowStringOne);
        values.put(KEY_BODY, rowStringTwo);
        values.put(KEY_rating, rating);
        return mDb.insert(GAME_TABLE_NAME, null, values);
    }
    public void deleteRow(long rowID)
    {
        try
        {
            mDb.delete(GAME_TABLE_NAME, KEY_ROWID + " = " + rowID, null);
        }
        catch(Exception e)
        {
            Log.e("DB ERROR", e.toString());
            e.printstacktrace();
        }
    }


    public GameDataBaseManager open() throws android.database.sqlException
    {
        mDbHelper = new DatabaseHelper(mCtx);
        mDb = mDbHelper.getWritableDatabase();
        return this;
    }

    public void close()
    {
        mDbHelper.close();
    }

    public Cursor getAllGames()
    {
        return mDb.query(GAME_TABLE_NAME, null, null,
                null, null, null, null);
    }

    public Cursor fetchGame(long rowId) throws sqlException
    {
        Cursor mCursor = mDb.query(true, GAME_TABLE_NAME, new String[]{KEY_ROWID, KEY_TITLE, KEY_BODY, KEY_rating}, 
                KEY_ROWID + "=" + rowId, null, null, null, null, null);
        if(mCursor != null)
        {
            mCursor.movetoFirst();
        }
        return mCursor;
    }

    public boolean updateDb(long rowId, String title, String body, String rating)
    {
        ContentValues args = new ContentValues();
        args.put(KEY_TITLE, title);
        args.put(KEY_BODY, body);
        args.put(KEY_rating, rating);

        return mDb.update(GAME_TABLE_NAME, args, KEY_ROWID + " = " + rowId, null) > 0;
    }

    public class DatabaseHelper extends sqliteOpenHelper {
        public DatabaseHelper(Context context) {
            super(context, DATABASE_NAME, null, DATABASE_VERSION);
        }

        @Override
        public void onCreate(sqliteDatabase db) {
            db.execsql(GAME_TABLE_CREATE);

        }

        @Override
        public void onUpgrade(sqliteDatabase db, int oldVersion, int newVersion) {

        }
    }
}

这是我尝试在其中插入项目的活动：

package com.herring.android.finalproject;

import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;

public class TopRatedActivity extends Activity {
    private Cursor gamesCursor;
    private ListView lv;
    private GameDataBaseManager mDbHelper;
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        mDbHelper = new GameDataBaseManager(this);
        mDbHelper.open();
        mDbHelper.addRow("Game", "Info", 0);
        setContentView(R.layout.toprated);
        fillData();

    }
    private void fillData()
    {
        gamesCursor = mDbHelper.getAllGames();
        startManagingCursor(gamesCursor);
        String[] from = new String[]{GameDataBaseManager.KEY_TITLE};
        int[] to = new int[]{R.id.text1};
        SimpleCursorAdapter games = new SimpleCursorAdapter(this, R.layout.toprateditem, gamesCursor, from, to);
        lv.setAdapter(games);
    }
}

任何帮助将不胜感激.

解决方法:

您的数据库中有一个名为“游戏”的表.但是它没有称为“标题”的列.您可以尝试删除整个数据库,然后重新创建它.

Call to undefined function cli_set_process_title,cli_set_process_title 信息 / 选项函数

Fatal error: Uncaught Error: Call to undefined function cli_set_process_title() in /home/wwwroot/es-task/taskServer.php:21 Stack trace: #0 /home/wwwroot/es-task/taskServer.php(155): SwooleTaskServer->__construct() #1 {main} thrown in /home/wwwroot/es-task/taskServer.php on line 21
